Renovating your kitchen or bathroom can be an opportunity to install a wall-mounted faucet. Take advantage of this opportunity to replace your old faucet with a mixer that will bring you comfort and aesthetics.

wall-mounted faucet is installed on two sealing pipes (one for hot water, the other for cold water). A sealing pipe is a special fitting used at the end of a pipe and embedded in a wall. The tap is connected directly to it.

Once the water supply pipes are mounted and embedded with their sealing pipe, you can install a wall-mounted faucet.

The installation of a wall-mounted faucet is the same regardless of its use (bathtub, shower, sink).

Before installing a wall-mounted faucet


Before installing a wall-mounted faucet, you must turn off the water with the stopcock if you have one; otherwise, at the water inlet of the house.

Then open a faucet to relieve the pressure in your pipes, and close it again when the water stops flowing.

Plug your sink or shower to prevent small parts of the faucet from falling into the pipe.

Measure for installation

5 Steps for Installing a Wall-Mounted Faucet

Measure the diameter of the sealing pipes that will allow you to install and secure your wall-mounted faucet. Also, measure their spacing. This will help you determine the size of the off-center fittings you will use.

If you are installing a wall-mounted faucet for your bathtub, you will need to install the shower hose and hand shower after the faucet is installed.

1. Place the off-center S-fittings

The sealing pipes are the ends of the water supply pipes that emerge from the wall’s surface.

Because the distance between the sealing pipes and the wall valve fasteners is often different, it is necessary to place off-center fittings or S-fittings. In addition, S-connections will allow you to adjust the horizontality of the wall valve when it is finished.

In general, eccentric fittings have a diameter of 15/21 on the sealing pipe side and 20/27 on the wall valve side. However, check the diameter measurements of the sealing pipes and the faucet ports to ensure you have the correct size.

    – Wrap Teflon around the threads of the off-center fittings in a clockwise direction. This will ensure a tight seal.

    – Screw the off-center fittings into the sealing pipes by hand.

    – Then, finish screwing them in with an open-end wrench.

Tip: You can replace the Teflon with wire coated with a sealing compound.

2. Prepare the installation of the wall faucet

Some elements, such as decorative rosettes or gaskets, must be installed before a wall-mounted faucet can be installed.

    – Place the decorative rosettes around the off-center fittings.

    – Insert the strainers with their gaskets into the holes of the wall faucet, which you will connect to the water supply.

3. Install the wall-mounted faucet

Your installation is now ready for the installation of a wall-mounted faucet.

    – Place a fiber seal between the off-center fittings and the nuts of the wall valve.

    – Screw the nuts of the wall valve to the off-center fittings by hand.

    – Finish tightening the nuts with the open-end wrench without forcing.

Tip: Protect the surface of your faucet with a soft cloth when tightening the nuts with the wrench.

4. Adjust the horizontal position of the wall faucet

The wall faucet you installed may not be perfectly horizontal. Use a spirit level to check this.

    – Place the spirit level on the faucet.

    – If the faucet is not horizontal, play with the tightness of the off-center fittings while examining the spirit level.

    – When the wall valve is horizontal, tighten the nuts on the valve a little more with the open-end wrench to finish securing it.

5. Check the installation

Once you have finished installing a wall-mounted faucet, you must check the installation for leaks.

    – Unscrew the filter from the wall faucet.

    – Turn on the water gradually and let it run.

    – If there are no leaks, refit the mousseur.

    – If you observe leaks:

        ◦ Unscrew the faucet nuts and check the positioning of the seals.

        ◦ If the leaks persist, check that you have correctly placed the off-center fittings.
